98 chevy k1500 fuel pump?

24 posts in this topic

Do the fuel pumps on these trucks just all of a sudden die?

Drove the truck Wednesday with no problems. It has been in the garage for two days. Go to start the truck today(Friday) and it won't fire. Of course it's the pheasant opener this weekend, so I filled up the gas tank.

Can't hear the fuel pump buzz when you turn the key like it usually does. I checked the fuses. Truck had 83,000 miles. Any other ideas to try?

You could always spray some starting fluid into throttle body and see if it will fire! This would rule in lack of fuel!

Hit gas tank with rubber hammer to see if you can get pump to work!

You can check fuel roll over cut off switch! I do not know where they are located on this truck, but owners manual should tell ya!

And ya, fuel pumps do just go like that!

Good luck!

83k is right on time.

Tapping with a hammer will work nine times out of ten. Usually works better while somebody cranks and somebody else does the pounding. If it fires up the likely candidate is a worn out commutator on the pump. Usually do to the lack of fuel filter replacement, which may not be your case. Pounding on the tank is not a fix and will likely only give you a few get out of jail free cards before it won't do the trick at all.

Chevy's don't have a fuel cut off switch. We have enough fun with fords version lets not give GM any ideas Shack!! grin.gif

The other thing to consider is the connector at the fuel pump may be burnt up. I do believe these are serviced as a module so the fuel pump side of the connector will be taken care of. Make sure you check the harness side off the connector for any discoloration of the pins. Typically they will turn a blue/black color. I think that year may have an updated harness pigtail/connector and and updated fuel pump module from the dealer (i have run into several times in the past but can't recall what years specifically it covers).

I had a '98....replaced the pump twice. No longer have it. Not sure if hitting the tank will work, the pump is in the top portion of the middle I believe....?

I finally disagree with airjer on something.... grin.gif....I'd say banging on the fuel pump DOESN't work 9 times out of 10 in this situation....

I have seen it work a couple times though!... cool.gif

When you replace the fuel pump, don't get the cheap aftermarket one, antie up and get oem. I know the oem's are a lot more expensive, but the will out last the aftermarkets. If you thought the original wore out fast wait till you put in a cheap one! My friend and I both put the cheap ones in, didn't get more than a year each on each one before we were replacing them again.

That, or after you just replace with aftermarte it does not work right away! Or sounds like a box or rocks when pump is turned on!

I would go OEM!

I use to have a Silverado and I replaced the fuel pump two times. First one was with the OEM one and the second one was with an aftermarket one. It didn't matter if it was the oem or aftermarket, both of them lasted a little over a year. I think it is just a bad design flaw on GM. Well, now its someone elses headache. grin.gif

Got it started by banging on the gas tank. Drove it to the shop to have them look at it on Monday.

I believe that there are a couple different style pumps for this model. I think I paid about 300 for my part (put it in myself), and that was supposed to be the more expensive of the pumps. Most shops will charge a few hundred in labor to install, so I would say about $600 would be a good ballpark estimate.

Theres alot of variation, most people I know that have replaced them have spent 700-1200 , depends on the shop and if they see you coming or not. 98 will be the more expensive pump because the pump and sending unit are one piece, the last aftermarket pump we bought was 300 bucks for a 98, verses 80 bucks for a 96, next time I do one it'll be OEM though, in retrospect.

I put the oem ac delco in. I looked online and they are MSRP of $550 for my truck. So I guess I'm in the ball park with labor. The shop said they used to put in the aftermarket ones, but stopped because they failed alot. They have not had many of the OEM pumps come back.

Just spent $600 for a '99 Tahoe fuel pump. $400 parts and $200 labor. Dumb question: Fuel filter was replaced too, right?

I had the fuel filter replaced at the same time.

Fuel filter is a must, when putting in a new pump!

A partially clogged or fully restricted fuel filter could be a cause of a failed fuel pump in the first place. To put in $500 or $600 into a fuel pump replacement and not put forward the extra $50 or $60 bucks for fuel filter, is a bad idea! I would pay the extra money or ask to have it done!

Good luck!

Side note: Your extended warranty can deny a fuel pump replacement (not cover repair costs), if you do not adhere to the factory maintenance schedule for fuel filter replacement!

My '98 cost me about $600 for pump and filter. I actually had about 140k on it, and the pump was whining but still working. I didn't want to have it go out on the road, so I had it replaced under my own terms smile.gif I ran it down to about 1/8 tank, then brought it in for replacement.

Now have 155k and 225k is my next target smile.gif then will move it to 300k. I hate payments wink.gif

fyi - I replaced my fuel filter I think 2 or 3 times prior, so maybe why mine lasted until 140k... I will keep doing that, thanks, good advice!

My 98 made it to 140 or so, the pump was getting loud so I replaced with a Napa. It went out within the year and they warrantied it. I was just on the hook for the labor. It is still working now and the guy at Napa said they had fixed the problem for what thats worth. It now has 200 on it and is still working well.

The fuel filter is not too bad to do yourself. I try to do mine once a year or so. Located drivers side about halfway back to the tank maybe. I usually end up getting a little gas on the floor and my arm... but it isn't bad

My 98 made it 39k, past warranty, not even a 1-1/2 yr old, I had changed the filter at 25k. Cost me close to a grand back then, too new at the time, no parts around.

      Nuts, I had to leave Fraser on Monday for some business and a trip, but I think your MO is the right one. However, there are a lot of small (10-12") fish on the reef tops as of Sunday. You might try deeper water just off the tops. I'm not a fan of bobber fishing (like to feel the bite) but it's been a consistent winning method. Dick

      Thanks for the info guys. We did end up going and launching at Beanies. Ten bucks to launch. Not too bad. There is a for sale by owner sign posted there but it's obviously private for now. As for the fishing, it was slow. Pulled the plug at noon and headed for the Mississippi. Did much better there.

      i wanted a yellow lab and got over ruled on the chocolate.  Great looking dog!  Does not look 115 pounds
    • JB18
          Thanks!  She is only 40 pounds at 9 months old.  Don't think she will get much bigger. I was hoping to talk with some people at the game farm next month to see if i can get a great price on a pre-buy program.    I have some pheasant feathers and she goes crazy when she see me grab them.  I need to find a field that the grass is not chest high to plant them or better yet get some game birds and tie the feet off and plant those.    If you drive by Round Lake and see a red Tundra stop in and say hello. I am there most nights when it gets this hot.

      Awese thread! I take our golden/lab mix to Round Lake for training also. This pic is from May when it was chilly. We're having an absolute blast working together. She's a sweet dog, will do anything to please me if she understands. Only thing I have to do before the season is somehow introduce her to gunshots and that's not easy without private land. Watching her barrel through the cattails to find that dummy is awesome.

      There are a few small Trout lakes in there as well but not sure how they bite in the summer? I've only Ice fished them.

      Thanks Cliff, weather looks dynamite so that's a good start!

      Finally making it up for our first trip of the year. Strictly walleye fishing in Frazer Bay with slip bobbers around the reefs. Appreciate any fishing reports. Thanks!

      I believe they take vets living in veteran homes around the area like Silver Bay veteran home ect
